frequently asked questions
What is R value
The 'R' value, or Thermal Resistance of a material, expresses the ability of a particular thickness of that material to resist heat flow.
The definition of R value is the reciprocal of the material's thermal conductance (C value).
The R value refers to the thermal resistance of a material, or assembly of materials such as the wall of a building, and is used to find the overall thermal resistance of an assembly of materials by simply adding individual component R values.
Do I need insulation?
It is worth investing in insulation for both comfort as well as easing your electricity costs.
EPS provides efficient, cost-effective insulation from sub-zero temperatures (freezer insulation) to the high temperatures around 80°C (on hot water pipes). In the construction and insulation industries EPS is the first choice for performance, sustainability and economy.
